A process for preparing Vilanterol includes a biocatalytic conversion of a ketone substrate to its corresponding alcohol, and then converting the obtained alcohol into Vilanterol. Polypeptides may be used for the biocatalytic conversion of the ketone substrate, such as 2-bromo-l-(2,2-dimethyl-4H-l,3-benzodioxin-6-yl)ethanone, to an enantiopure alcohol, (R)-2-bromo-l-(2,2-dimethyl-4H-l,3-benzodioxin-6-yl)ethanol for the preparation of Vilanterol. Also disclosed is vilanterol tartrate and solid state forms thereof for use as medicaments and for the preparation of other vilanterol salts, or of vilanterol, solid state forms and/or formulations thereof. Also disclosed is a process for the preparation of pharmaceutical formulations including vilanterol tartrate and solid state forms thereof, as well as a method of treating a person suffering from COPD and asthma by administering a therapeutically effective amount of any one or a combination of vilanterol tartrate and solid state forms thereof or a pharmaceutical composition and/or formulation comprising vilanterol tartrate and solid state forms thereof.
制备维兰特罗的过程包括将酮底物进行生物催化转化为其相应的醇,然后将得到的醇转化为维兰特罗。多肽可用于酮底物的生物催化转化,例如将2-溴-1-(2,2-二甲基-4H-1,3-苯并二氧杂环己-6-基)乙酮转化为对映纯醇,(R)-2-溴-1-(2,2-二甲基-4H-1,3-苯并二氧杂环己-6-基)乙醇,用于制备维兰特罗。还公开了维兰特罗酒石酸盐及其作为药物用途的固态形式,以及用于制备其他维兰特罗盐或维兰特罗、固态形式和/或其制剂。还公开了一种包括维兰特罗酒石酸盐和固态形式的制备药物制剂的过程,以及通过给予治疗有效量的维兰特罗酒石酸盐和固态形式的任一种或组合,或包含维兰特罗酒石酸盐和固态形式的药物组合物和/或制剂,来治疗患有慢性阻塞性肺病(COPD)和哮喘的人的方法。
